Instrument Capabilities

This Langmuir-Blodgett deposition system is designed for forming and transferring monolayers and multilayers onto substrates. It provides precise control of surface pressure, barrier movement, and substrate dipping speed for controlled thin-film deposition.

Model: KSV MiniTrough

Features

• PTFE trough: Surface area of 273 cm² (L364 × W75 × D7 mm³), with a dipping well measuring L37 × W37 × D64 mm³ and a subphase volume of 280 mL.
• Barriers: Hydrophobic PTFE and hydrophilic polyacetal (Delfrin) barriers are used to adjust the surface pressure. Barrier speed ranges from 0.01 to 400 mm/min.1
• Surface pressure measurement: Measured using the Wilhelmy plate method with either a platinum plate or paper. The balance has a total measurement range of ±2000 mg. With the platinum
• Wilhelmy plate, 1 mN/m corresponds to 4 mg.
• Deposition system: Dipping arm with a speed range of 0.1–85 mm/min.
• Film transfer: Supports monolayer and multilayer transfers.
• Operation: Software-controlled operation.
• Substrate size: Maximum substrate size of 60 × 35 mm.
